We experimentally demonstrate that monolithic perovskite/silicon tandem solar cells possess a superior reverse-bias resilience compared with perovskite single-junction solar cells. The majority of the reverse-bias voltage is dropped across the more robust silicon subcell, protecting the perovskite subcell from reverse-bias-induced degradation. These results

However, we highlighted that the tandem solar cells' resistance to the reverse bias is not universal but depends on the electrical and optical design of the device. In fact, the protection from silicon is effective if the bottom cell features a breakdown voltage in the range of −40 V along with a high shunt resistance.

A solar cell can become reverse biased (i.e., can operate at a negative voltage) when it produces significantly less current than the other cells that it is connected in series with, for example, in the solar modules.
